Abstract (en)

A current mirror circuit (20) formed of a PNP (NPN) transistor (201) employs as its load an I<2>L circuit (30), an injector (31) of the I<2>L circuit (30) being common with those of another group of I<2>L circuits (40), and a predetermined current being derived from the PNP (NPN) transistor (201) of the current mirror circuit (20).
